Each
of the binary pair travels at a significant velocity when compared
to one another (unlike a singular system). So when we take into account
the force of gravity itself having velocity then we must realize that
the origin of the pull of gravity cannot be at the same position as
the body itself.

In
light of this, just using your imagination, try and figure out a rough
idea of how the shape of the orbit changes with the gravity having
velocity..

BOGVOS:
Binary-Orbit-Gravity-Velocity-Out-Spiral

.

This
needs to be explained with a much simpler approximation:

At about 2500km
apart, a binary pair of equal mass, (both 33 solar masses) travels
at roughly one-tenth the velocity of light. So the delay in gravity
causes a divergence between the gravity origin and the body itself
of about one-tenth the distance between them. There is thus a gap
of about 250 km between where the body actually is and where it was
when it generated the gravity that eventually reaches the opposing
body.

Because the bodies
travel at 1/10th the velocity of light, the gap between the body and
the gravity origin is about 1/10 of the distance between the pair
of bodies.

That
is a very big gap, proportionally speaking. And it is simple to verify
the computation with simple arithmetic. The gap is demonstrated in
the graphic above by the gap between the body and the orbit line (at
the numbers 2 & 1).

There
are many conclusions that can be attained from this. Not the least
of which is that the LIGO group have not solved the many-body-problem
which is the engine driving the OGS11 computer models. In retrospect
it is astonishing that nobody else seems to have realized that the
pair will spiral outwards..
